Guardian, I could try to get a doctors note. However it needs to be cooled for the whole trip. I don't have German health insurance anymore so if I go see my former GI I would have to pay him out of pocket. I'm not even sure if they let me do that. In Germany you're required to have health insurance but I'm not living there anymore. I might have to save this for another trip.
Edit: Actually I can order it without a prescription. It's worth looking into. Thanks for bringing it up.
